Is It Mold?
In many cases, yes.
White mold is one of the most common forms found on leather goods.
It often appears as:
- White fuzzy spots
- Powdery patches
- Cotton-like growths
- Circular white colonies
- Dusty-looking areas
Many people initially think the substance is dirt or dust.
Then they try wiping it
